Ostracodos do Toarciano de Rabaçal (região de Coimbra): novos dados biostratigráficos

Abstract

Ostracods from 58 marl samples from the Toarcian of Rabaçal (Coimbra, Portugal) were studied. This marly limestone series, deposited in a deep marine environment, has abundant benthic and nektonic macrofauna, and it is accurately constrained as regards to biostratigraphy by amonnoids and calcareous nannofossils. The new results from the ostracod fauna allows the establishment of a new biostratigraphical scale for this group which, compared with the previous scales, allows changing some data, namely the Metacopina extinction event.

Foram estudados os ostracodos de 58 amostras margosas representativas de toda a série toarciana do corte de Rabaçal. Esta série margo-calcária, depositada em meio marinho profundo, é rica em macrofauna nectónica e bentónica, estando bem calibrada biostratigraficamente por amonóides e nanofósseis calcários. Os novos resultados agora obtidos para os ostracodos permitem estabelecer uma escala biostratigráfica para este grupo, aferida às anteriores, alterando alguns dados, nomeadamente quanto ao evento de extinção dos Metacopina.
